Application filedluly 24, 1908. Serial No. 445,067;

To all whom it may concern:

Be it known that I, WILLIAM H. HAMMoN, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain newand useful Improvement in Pipe- Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to pipe couplers for connecting the meeting ends of ipes and its object is to provide a simple, urable, and inexpensive coupler, whereby the meeting ends of pipe may be quickly joined together.

A further object of my invention is 'to' provide means whereby the joint may be readily broken or opened without destroying the coupler ring or pipe sections, and it consists in the construction and combination of parts as will be hereinafter more fully set forth, reference being had to the accompanying drawings, in which- 1 Figure 1 is a longitudinal sectional view illustrating my invention; Fig. 2-is a longitudinal transverse sectional view of the couplerring; and Fig. 3 is an enlarged frag- -mentary sectional view to be hereinafter referred to. v I

I will now describe my invention so that others skilled in the art to which it appertains may understand and construct the same.

In the drawings, the reference. numerals 2 and 3 represent the adjacent ends of two' pipe, sections. These end sections are surroundedby the steel coupler ring 4 which is provided at each end with an annular enlargement 5 adapted to receive the gasket 6. This enlar 'ement 5 is formed with a straight 7 face 7 an an inclined or beveled face 8. The gasket 6 is rovided with a correspondingly inclined ace 9 which is adapted to bear against the face 8, and is held in place by means of the follower ri 10 which consists of the inwardly pro ecting annular flange 11 adapted to bear against the gasket 6, and the radial flange 12 throu h which the connecting bolts 13' are adapte to pass. The inner face of the flange 11 is slightly inclined as indicated by the numeral 14 (see Fig. 3) and. bears against the similarly inclined outer face of the gasket 6. 'The purpose of this inclined face 14 is to prevent undue lateral spreading of the gasket when it is forced home by the follower-ring. Consequently a more eflective seating of the case were the gasket allowed to s read laterally and become missha d. T e. opening in each follower ring is at 15 so that the pi e sections ma be readily fitted together. 'I he steel coup ing ring 4 is provided 'on its inner "face midway'fbe- I tween its ends with two diametrically op o sitely arranged separately formed frangi le endwise movement of the pipe sections when being placed within the coupler ring and causes theirends to sto midway between the ends of the coupler ring. These lugs 16 are secured to the coupler rin 4 by welding in any suitable manner, so t at when it is desired to break or open thejoint, the lugs may be readily broken off by causing the the pipe. This, however, does not prevent further using of the coupler ring, as it is apparent that the ring ma again he slid into position and locked in the usual manner by means of the gaskets and follower-rings. The advantages of m appreciated by those ski led-in-the art. By my invention I am able to form a joint that may be readily broken without destroying either the coupler or the pipe sections.

Having thus describedmy invention, what I claim and desire to secure-by Letters Patent is; v
